Excellent communication on specs
I wasn't sure about the tolerance requirements for my application. Their engineering team helped clarify the best specifications before production started. Highly recommended.

Robust construction
Used this for a high-torque transmission setup. The rectangular spline design holds up well under stress with no signs of wear after three months of heavy use.

Good value for custom work
Pricing is competitive for custom machining. The only reason for 4 stars is that the packaging could be slightly more robust for international shipping, though the part arrived undamaged.

Perfect fit for our retrofit project
We needed a specific involute spline shaft for an older machine, and they delivered exactly to our drawings. The surface finish was excellent, and the dimensions were spot on.

Solid quality, slight delay
The bushing itself is very durable and machined well. There was a two-day delay in shipping due to custom heat treatment, but the support team kept me informed.

Great for single piece orders
It is rare to find a supplier willing to make just one custom part without a huge markup. The quality is industrial grade, and shipping was faster than expected.
Q: What is the maximum length you can machine for a single piece order?
A: For single-piece custom orders, our current CNC capabilities allow for lengths up to 2.5 meters. For requirements exceeding this, please contact us directly to discuss segmented solutions or specialized tooling.
Q: Can you produce a spline shaft with a mixed profile, or is it strictly one type per unit?
A: Each individual shaft is manufactured with a consistent profile (either fully rectangular or fully involute) to ensure mechanical integrity. However, we can produce a batch containing both types if your order requires multiple variations.
Q: How do I submit my technical drawings for a custom quote?
A: You can upload your CAD files (STEP, IGES, or PDF drawings) directly through the 'Custom Request' button on this product page. Our engineering team typically reviews and responds with a quote within 24 hours.
Q: Do you provide material certification documents with the shipment?
A: Yes, every custom order includes a Mill Test Certificate (MTC) detailing the chemical composition and mechanical properties of the raw material used for your specific part.
Q: Is the black oxide coating suitable for outdoor agricultural equipment?
A: While black oxide provides good corrosion resistance and reduces glare, for harsh outdoor agricultural environments, we recommend upgrading to zinc plating or nitriding for enhanced durability against moisture and chemicals.
